Hello,

Any Recommendations on a disc break conversion for my 68 Charger?

Also I would like to change the stance. What size tires can I put on the front and rear to add a more aggressive look?
 
I have used Master Power Brakes for a kit for my 1966 Charger, they worked fine, but the GM style booster, and master just BUGGED me being in the Mopar engine bay.
I also put 3 other MBP kits on for customers, and they work well.
I put together a sweet kit for my last few cars, using factory parts. 11.75 rotors, with pin type calipers.(cost me about $600)
I guess it depends on what you plan on doing with the car, and how much money you want to spend, and how well you want to stop.
My buddy has a SWEET multi piston caliper, powder coated Wilwood 4 wheel disc set up on his 1969 GTX, with drilled and slotted rotors.
I have slotted rotors, on my 1969 Charger, but again using factory parts, and stock rear drums.
What is your budget, and how do you intend on using your car?
 
welcome to FBBO
15" wheels & maybe a 1/4" spacer "if need be"
to clear calipers offsets etc.
will cure most of the conversion disc. or any clearance problems
with the correct wheel backspacing you can easily fit
a p295/50/15 under the rear, 8-9" 5"-5.5" BS or even 10" wide rim
or if you don't want that aggressive do a p275/60/15
a p255 or p245/60/15 will clear all the suspension components
7-8" rim even with a std. backspacing
easily on the front too,
the wheels inside back disc caliper clearance needs to be checked,
again depending on what brake kit you choose
usually, something like a 1/4" spacer can help it
calipers clear the inside of the wheels, "if you even need them"

there's many, many, many threads here on FBBO
in specific forums too
you can use the search feature on the top right of the page
to search out many brakes (or wheel & tires combos) applications threads

good luck

I use Dr. Diff for all my disc brake conversions. Great guy to deal with, really knows his stuff.

Actually I think your right, they are based on Mopar slider style calipers, but they are knock off calipers not OE so they kinda look like a GM caliper....

From the comments/Q&A:

"The calipers are a Mopar caliper and any parts store will have replacement pads for caliper number 4103 and 4104 which you can also look up on the internet under those part numbers."

I plan to take the car to a few shows. But mostly just for fun. I don’t really have a hard budget. I just want to do it right the first time. Would you recommend all 4 or just front. My mechanic is only recommending the front.
 
Installed this kit https://piratejack.net/66-70-b-body-71-74-e-body-o-e-m-style-disc-brake-kit-booster-1/
uses A body calipers and a Bendix style booster. Looks very close to original.

Welcome from S.E. USA! I just recently rebuilt my front end, and did a front power disc brake conversion on my 70 Charger, utilizing a rebuild kit and power booster kit that I bought on eBay; https://www.ebay.com/itm/Front-End-Suspension-Master-Rebuild-Kit-Fits-1970-1972-Dodge-Charger-Coronet/372584456857?ssPageName=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649; https://www.ebay.com/itm/Mopar-8-Dual-Power-Brake-booster-1-1-8-bore-master-Kit-for-A-B-E-Body-NEW/331762794902?ssPageName=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649, you'll also need a disc/drum proportioning valve, https://www.ebay.com/itm/67-70-Mopar-B-body-Disc-Drum-Brake-Distribution-Brass-Block-Proportioning-Valve/190820429717?ssPageName=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649 I had already collected rotors from a 73 Challenger, because I wanted to retain my Magnums, as they cannot be used with the bigger 'C' body rotors. O'Reilly's Auto Parts sold complete rotor and caliper kits, so I went with them. I upgraded to 15 x7 1 piece Dynacorn alloy Magnums, with 225/R75 15 Hankook tires. This combo filled up/out the wheel wells and gave my car a more aggressive stance. No clearance or rubbing problems, no spacers. See the pictures.. Hope this helps you out! :)

Welcome from Missouri!!
 
I went to scrap yard and matched a booster that would fit he firewall, and mad a adapter plate
I have 14hg so didn't want a hard pedal, let me tell you the way I have it set up it can lock the wheel top with very little pressure . that s the issue when you but hp cams in engine and get slow vacuum. ether run hydra boost or buy external vacuum pump
